Lettersocial.com is a social network that is all about sending letters to your friends. More beautiful than emails, but simpler than most of the social networks, you just have to create your account, and send letters to your friends (with their usernames). When you receive a letter, you are being notified : a mail is sent to your adress, and there's the number of letters that you have received just next to "letterbox" on the menu bar. Of course, all kinds of SMS languages, intentional orthograph mistakes are discouraged by the community. Have a good time on Lettersocial.com !
